update_pantry

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description implies data mutation but does not disclose any behavioral traits: no mention of side effects, required permissions, or whether the update is incremental or replaces the entire pantry. With no annotations, the description should provide more context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

While the description is short, it is under-specified and sacrifices clarity for brevity. The single sentence does not earn its place as it fails to convey essential information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of annotations, output schema, and parameter documentation, the description is severely incomplete. It does not explain the tool's behavior, return value, or operational context for a mutation tool with multiple parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has three parameters with 0% description coverage, and the tool description provides no explanation of what 'add_items' or 'remove_items' represent, their expected format, or how they relate to 'canonicalise'. This leaves the agent guessing about usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the verb 'canonicalise and update' which is somewhat specific, but 'canonicalise' is unclear jargon. The resource 'pantry staples' is vague and doesn't clearly distinguish from sibling tools like 'get_pantry'. A clearer statement like 'Add or remove items from the pantry list' would improve clarity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives such as 'get_pantry' for reading or 'add_recipe' for adding a recipe. The description does not include any context about prerequisites or scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
